APS1086 - 600mA Synchronous Step-Down Converter

General Description

The APS1086 is a 2 MHz constant frequency, high efficiency, slope compensated current mode PWM step-down DC-to-DC converter.

The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode.

Key Features

  • a Power Saving Mode which reduces quiescent current to just 30µA and significantly improves efficiency at light load. The APS1086 is offered in a low profile (1mm) 5-pin, SOT package, and is available in an adjustable version and fixed output voltage of 1.2V, 1.5V and 1.8V.

APSemi APS1086 2MHz, 600mA Synchronous Step-Down Converter with Low Quiescent Current GENERAL DESCRIPTION The APS1086 is a 2 MHz constant frequency, high efficiency, slope compensated current mode PWM step-down DC-to-DC converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The APS1086 can operate from a 2.5V to 5.5V input voltage and is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery. It can supply 600mA output current and can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. The APS1086 features a Power Saving Mode which reduces quiescent current to just 30µA and significantly improves efficiency at light load.
